31. Buick GS 455

The Buick GS 455 is an interesting car in muscle car mythology. As with all other GM muscle cars, the Buick Gran Sport was limited to 400 CID. But, in 1970 when GM lifted its ban on engine displacement, Buick decided to introduce one strong model they simply named the Gran Sport 455.

This car featured the famous 455 V8 they rated at 360 HP. It could launch this big, heavy car to 60 MPH in just around 5.5 seconds. This was lightning fast in 1971, and its speed is still respectable today.
